What Are Optical Homogenizer/Diffusers?

An optical homogenizer is an optical component that makes the intensity profile of a light beam more uniform. This means that local intensity variations in the beam profile are eliminated, and the overall envelope of the beam becomes smooth. Homogenizer working principle Homogenization is done by diffusing the light at controlled angles, scrambling the phase, … Continue reading

Principles of Diffractive Homogenizers

A beam homogenizer, also called an optical homogenizer or diffuser, is an optical component that generates a uniform distribution from the input beam projected onto it. The laser homogenizer applies a random or quasi-random modification to a single-mode or multi-mode input beam to diffuse the irregularities. Therefore the output beam has a well-defined near constant … Continue reading
